· Advice for firefighters

· Protective equipment: No special measures required.

Accidental release measures

· Personal precautions, protective equipment and emergency procedures

Wear personal protective equipment. Keep unprotected persons away.

· Environmental precautions:

Prevent from spreading (e.g. by damming-in or oil barriers).

Keep contaminated washing water and dispose of appropriately.

Do not allow product to reach sewage system or any water course.

Prevent seepage into sewage system, workpits and cellars.

Inform respective authorities in case of seepage into water course or sewage system.

Do not allow to enter sewers/ surface or ground water.

· Methods and material for containment and cleaning up:

Absorb with liquid-binding material (sand, diatomite, acid binders, universal binders, sawdust).

Dispose contaminated material as waste according to specifications.

Ensure adequate ventilation.

Do not flush with water or aqueous cleansing agents

Handling and storage

· Precautions for safe handling

Store in cool, dry place in tightly closed receptacles.

Keep away from heat and direct sunlight.

Do not refill residue into storage receptacles.

Ensure good interior ventilation, especially at floor level. (Fumes are heavier than air).

Prevent static electric sparks.

Prevent formation of aerosols.

· Information about fire - and explosion protection:

The vapour may be invisible and is heavier than air. It spreads along the ground and may enter sewers and basements.

Heating of container(s) will cause pressure rise with risk of bursting and subsequent explosion (BLEVE).

Earth container to avoid electric sparks, especially in contact with flammable substances.

Traces of flammable substances may collect in the steam chamber of enclosed systems. Keep clear ofignition sources.

· Conditions for safe storage, including any incompatibilities

· Storage:

Requirements to be met by storerooms and receptacles: Store in a cool location.

· Further information about storage conditions:

Store in cool, dry conditions in well sealed receptacles.

· Specific end use(s): Not applicable.

Exposure controls / personal protection

Control parameters

· Ingredients with limit values that require monitoring at the workplace: The product does not contain any relevant quantities of materials with critical values that have to be monitored at the workplace.

· Additional information: Valid lists at time of creation were used as basis.

Exposure controls

· Appropriate engineering controls: No further relevant information available.

· Personal protective equipment:

· General protective and hygienic measures:

Keep away from foodstuffs, beverages and feed.

Immediately remove all soiled and contaminated clothing.

Wash hands before breaks and at the end of work.

Avoid contact with the skin.

Avoid contact with the eyes and skin.

· Respiratory protection:

In case of brief exposure or low pollution use respiratory filter device. In case of intensive or longer exposure use self-contained respiratory protective device.

Respiratory protection in case of dust.

· Protection of hands:

Protective gloves.

Check the condition of the gloves prior to each use.

The glove material has to be impermeable and resistant to the product/ the substance/ the preparation.

Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation.

Preventive skin protection by use of skin-protecting agents is recommended.

· Material of gloves: Fluorocarbon rubber (Viton)

The selection of the suitable gloves does not only depend on the material, but also on further marks of quality and varies from manufacturer to manufacturer. As the product is a preparation of several substances, the resistance of the glove material can not be calculated in advance and has therefore to be checked prior to the application.

Recommended thickness of the material: >= 0.35 mm

· Penetration time of glove material

EN 420: Minimum requirements for efficiency level 1 for all groups.

The exact break through time has to be obtained from the manufacturer of the protective gloves and has to be observed.

For the mixture of chemicals mentioned below the penetration time has to be at least 480 minutes (Permeation according to EN 374 Part 3: Level 6).

· For the permanent contact gloves made of the following materials are suitable:

Fluorocarbon rubber (Viton)

· Not suitable are gloves made of the following materials:

Butyl rubber, BR

Natural rubber, NR

Leather gloves

cloth gloves

PVC gloves

· Eye protection:

Face protection

Tightly sealed goggles

· Body protection: Solvent resistant protective clothing
